I preferably construct-this passagel by providing a groove 23 in theupper surface of the shoe 22, which groove forms a trough extending theentire length of and adjacent the outer edge of the shoe. It will' benoted that the-shoe is p rovided with a retaining flange 24 along theoutside edge, and the veneered end panel 10 abuts the top surface of theshoe just inside this retaining flange 24, the trough 23 beingpreferably located directly beneath the lower edge of the veneered endpanel. i

Under" abnormal conditions the moisture drips down onto the shoe 22 andgradually creeps along the top surface ofthe shoe towards the end panel.It will drip into the trough 23 which extends from the front to the backof the box. The moisture is permitted lto drain` off through the troughto a point exterior of the box, where it is evaporated.

Various changes in construction maybe made without departing from thespirit of the invention as pointed out in the appended claims.

What I claim is: .f

J1. A refrigerator cabinet constructed of a plurality of members joinedtogether, a shoe providing-a base for said cabinet and secured ryingaway moisture which collects adjacent the joint between the abovementioned cabi` net members.

2. A refrigerator cabinet constructed of a plurality of frame'membersjoined together, and a shoe providing a base for said cabinet beneathsaid frame members, said shoe having a trough in the upper surfaceleading to an' exterior point of the cabinet.`

3. A refrigerator cabinet including a bottom wall, an end panel, a shoeblock secured thereto ladjacent its lower edge forming a support for thebottom wall of the cabinet,

and a shoe secured to the lower edge of said end panel and provided witha trough leading to an exterioi-.point ofy the cabinet.

4. A 'refrigerator cabinet including a bottom wall, an end panelconstructed of a plurality of layers of Wood glued together, a shoeblock secured against the inside face of said panel for supporting thebottom wall of the cabinet, and a shoe .secured to said shoe block andend' panel, said shoe being 70 provided with means for carrying awaymoisture that collects in the interior of the refrigerator wallstructure.

5. A refrigerator cabinet including a bottom wall, an end panelconstructed of a. plu- 75.

6. A refrigerator cabinet including a bottom wall, an end panelconstructed of a plurality of layers of wood glued together, a shoeblock secured to-'tl-.eninder surface of said bottom wall and theinner-surface of said end panel, and a shoe securedfbeneath said shoeblock and said end panel,l s aid\shc e`H being provided with a trough inits upper surface running from the front totheA back of the cabinet andlocated adjacentthe lower edge of the' end panel for providing agains-lsage in said refrigerator wall structuretck` permit air to absorbmoist-ure collecting at 95 an interior point of said wall structure andto drain off excess amounts of moisture under abnormal moistureconditions.

In testimony whereof, I hereunto affix my signature.
